Dr. Gerrit L. Verschuur is best known for his work in radio astronomy. In his primary field of study Verschuur pioneered the measurement of the interstellar magnetic field using the 21-cm Zeeman effect technique. He is also co-inventor on a dozen patents, his favorites being on ways to read bar codes inside sealed envelopes.
